Title: Reduced height dust valve
Inventor: CARPENTIER URGEL R
IPC: F16K1/20
Filed: 1987-05-29
Granted: 1992-01-07
Abstract: ABSTRACT         A double dump airlock valve having a reduced headroom requirement comprising an actuator shaft mounted at the bottom of the valve body, a link from the actuator connected to the flapper in an off centre position. The edge of the flapper and the corresponding edge of the seat define radiuses for pivotal movement against one another.  The flapper is opened by initial-ly sliding and then pivoting at the radial surfaces as the plate swings open until a spacer lug thereon encounters the actuator.          This breaks the vacuum thus requiring less power and also serves to jar loose compacted particulate material.  The action is reversed upon closing so that the wiping of the seat as the flapper closes tends to wipe particles from the seat to achieve a fully aligned seal.

Title: Box
Inventor: WAKELIN THOMAS C V
IPC: B42F17/08
Filed: 1987-06-05
Granted: 1991-03-26
Abstract: ABSTRACT     A BOX     A box for storing thin slightly compressible objects, in particular floppy disks, has an inner part and an outer part.   In an open position of the box, the inner part is substantially upright for support of the disks in a position for selection of one of them.   The inner part has a foot member beneath the disks and a stem member behind the disks.   A movable member is pivoted at pins to the inner part at a position spaced above the foot.   This member has a lower portion beneath the pivot pins and an upper portion thereabove.   On movement of the upper portion away from the stem member, the lower portion moves crosswise of the foot and compresses the disks locally between itself and the stem which acts as a reaction member.   This action causes the disks to fan out above the pivot pins for selection amongst them.   The upper portion of the movable member restrains the disks from falling forwards out of the box.

Title: Immersion cooling safety monitoring system
Inventor: CURTIS RONALD L
IPC: G06F1/20
Filed: 1987-11-25
Granted: 1991-05-14
Abstract: Abstract of the Disclosure A safety monitoring system for an immersion cooling system of a large, high-density electronic assembly such as a supercomputer protects against the possibility of toxic gas formation due to overheating and breakdown of the cooling liquid caused by a system failure.  Voltage taps are provided on all of the power supply bars in the computer, and are brought out to the monitoring system, which scans them and compares them against predetermined voltage tolerance limits.  A catastrophic electronic failure or short circuit within the computer could produce arcing that could cause local high temperatures and coolant breakdown.  The reduction in voltage caused by such failure would immediately be detected by the monitor, which would operate to shut down power to the computer, and activate a safety ven-tilation system prior to any substantial production of toxic gas.
